9、ing,there is a need for standardtests by which joints of various substrates and adhesives can becompared.This test method is intended to meet such a need.4.2 This test method is limited to test temperatures belowthe softening point of the subject adherends,and is notintended for use on anisotropic a
10、dherends such as reinforcedplastic laminates.4.3 The misuse of strength values obtained from this testmethod as design stress allowable values for structural jointscould lead to product failure,property damage,and humaninjury.4.4 The apparent shear strength of an adhesive obtainedfrom a given small
11、single-lap specimen may differ from thatobtained from a joint made with different adherends or by adifferent bonding process.The normal variation of temperatureand moisture in the service environment causes the adherendsand the adhesive to swell and shrink.The adherends andadhesive are likely to hav
12、e different thermal and moisturecoefficients of expansion.4.5 Even in small specimens,short-term environmentalchanges can induce internal stresses or chemical changes in theadhesive that permanently affect the apparent strength andother mechanical properties of the adhesive.The problem ofpredicting
13、joint behavior in a changing environment is evenmore difficult if a different type of adherend is used in a largerstructural joint than was used in the small specimen.4.6 The apparent shear strength measured with a single-lapspecimen is not suitable for determining allowable designstresses for desig
